Tech stock have been getting hit--except for these names

Despite the recent selloff in the broader tech space, semiconductor companies specializing in chips that power devices like smartphones and tablets have held up well, analysts say.

The Philadelphia semiconductor index, for example, is up 1.4 percent since early March—and by more than 9 percent since the lows of early February—while the tech-heavy Nasdaq has lost nearly 6 percent during that period.
